Medium Voltage

For Protection of Motors and Systems Against Overheating

The SI-TPR6 is designed to protect electric motors, transformers, and other systems from overheating.

The SI-TPR6 has up to 14 temperature inputs that can be programmed to measure thermistors (PTC or NTC) and RTDs (Pt100).

Advanced Features

  • Advanced microprocessor based circuitry
  • Display of operating RTD or Thermistor Data, Fault and Statistics
  • Programmable inputs and outputs
  • RS-485 communication with MODBUS protocol
  • Easy installation and friendly operation
  • Two level protection for Alarm and Trip
  • Selection between Trip and Trip fail-safe
  • Analog output related to any input or input combinations
  • RTD / Thermistor selection – RTDs 100 ohm Platinum (PT100)
  • Thermistor – PTC or NTC
  • Disconnected sensor protection

Protection Features

  • RTD / Thermistor – two levels for each input
  • Thermistor PTC / NTC selection
  • Over temperature Alarm & Trip to each input
  • Continuous analog output signal
  • External fault 1 and 2

Protection Functions

Exact input for any of the following items:
  • Alarm only – Relay A
  • Trip only – Relay B
  • Fan (Trip, Alarm)- Relay C
